WINDOW CONSTRUCTION Application flleiAukixstlB, 1927. serial no.213,729.

This invention relates to window construction and has for its object toprovide a window in which the sashes can be securely clamped in place inclosed position or any position of adjustment, but may be loosened so asto be freely movable when it is desired to open or close the window.

A further object of the invention'is to provide a window of this classwherein the mech anism for holding the window in fixed'position extendsthroughout the entire length of the window and not only makes a tightconnection with the window throughout the length of the window, but alsotightly engages the window frame and thereby makes the window weatherandwind-proof to an extent impossible with windows operating in fixedguideways and which must therefore be more or less freely movable.

A further object of the invention is to provide a window of thischaracter which costs but little more than an ordinary sliding sashwindow construction, which may be readilynstalled inhouses alreadybuilt, as well as in new buildings, and'which is adaptable to eitherwooden or metal window frames- A further object of tlfe invention is toprovide a window construction of this character which has no unsightlyparts and which in effect is indistinguishable from ordinary slidingsashwindows except for the'provision of a small operating member whichmay be a small handle, a thumb screw or similar inconspicuous part. I Itmay be a window of more than two sashes and may be used for theoperation of shutters or screens. It may\be I used for windows inrailway or other cars as well as in any type of building. It may be usedfor windows of one movable pane of glass as in an automobile.

In the accompanying drawings I have disclosed my invention applied to awooden frame sliding sash window of usual construction.

In said drawings,

Fig. 1 is a vertical sectional view through one side of a window frameequipped with my improvement and showing the adjacent portions of thesashes in-elevation;

Fig. 2 is vertical section at right angles to Fig. 1, on the line 2-2thereof;

Fig. 3, is a pers ective view artly in section on an enlarge scale ofthe ower portion of the window;

Fig. 4 is a sectional view on line 4-4 of Fig. 1 showing the partsadjusted to loosen thedwindow so that 1t may be raised or lowere F-i 5is a similar view with the parts adjuste to the ositionfor clamping thewindow tight; and

Fig. 6 is a sectionalview on an enlarged scale'on line 66 of Fig. 1.

Referring to the drawings, 1 is the vertical member of the house wall atone side of the window opening, ,and 2 and 3 indicate, re-;

spectively, the upper and lower sashes formmg the window. The sashes2'and 3 are of a width somewhat less than the space between with strips7 and 8,

the member 1 and the corresponding member the principal parts of myinvention and consists preferably of sheet metal, such as pressed steel,in the form' of a double channel. The sash guide 9 is of a length toextend from the bottom member 10 of the window frame to the top member11, and the twd flanges at the edges of the sash guide extend,respectively, between the spaces between the-sash frames and theadjacent strips 7 and 8. The inner faces of these flanges, that is, thefaces adjacent the sashes, are inclined or beveled as shown, and theadjacent ortions of the sashes are correspondingly eveled so that as thesash guide is forced outwardly or toward the sashes the two sashes willbe clamped together. The middle strip 12 maybetapered also, butispreferably flat, so that formed not only between the sas the sash frameswill be drawn toward each other by the-clamping'action of the sash Anysuitable mechanism may be em loyed for shifting the sash guides towardan y from the sash frames to lock the sashes in position in the mannerdescribed. The mechanism shown in the drawing consists of a rectangularsheet metal frame 13 of a length slightly less than the height of thewindow and with its two vertical members in engagement with the rearface of the sash guide 9 at its edges: The frame 13 is verticallymovable and has attached to it a series of rods or bars 14 whose endsare cylindrical, as shown, and project beyond the edges of the frame 13and the sash uide 9, in position to engage the inclined'facesof camblocks 15 attached to the inner faces of the frame members .5 and 6adjacent the ends of the bars 14.

Three bars 14 are shown but the number may obviously be greater or lessif desired, depending primaril upon the height of the window. The bloc s15 are thicker at the bottom than at the top so that when the frame 13is lowered it will thrust the sash guide toward the sash frames, andwhen elevated will permit the sash frames to be withdrawn and therebyfree the sashes.

To insure the positive release of the sashes when the frame 13 is raisedthere is provided, as shown in Figs. 3 and 6, a spring device comprisinga bar 16 attached to the back of the sash guide 9 at its middle part andwith its ends bent outwardly to clear the frame 13 and extend beyond theframe to thereby provide a space between the ends of the bar and thestrips 7 and 8. Each end of the bar carries a cup or spring guide 17 inwhich is seated a spring 18 working between the bottom of the cup and aplunger 19 whose head presses against the inner face of the strip,whereby the spring will be compressed by the movement of the sash guidetoward thesash frames and when released will force the frame outwardlyto positively free the sash frames. The extent of movement of thesprings is limited by pins 20 inv the end of the plungers. Spring; bars16 are provided at both the top and bottom of the window, as shown inFig. 2, and obviously, of course,

other bars may be provided at intermediate points, particularly withhigh windows.

Any suitable mechanism may be employed for raising and lowering theframe 13. As

a convenient device for this purpose I have illustrated a lever 21fulcrumed at'its far end to the inner face of the outer sash frame--Figs. 2 and 3. This pivot opening is sufiiciently large to give thenecessar play in raising or lowering the lever. The ever is' pivoted tothe bottom cross. member of frame 13, and its outer end terminates in ahandle 22 whereby it may be readily operated. A block 23 is attached tothe lever back of the handle and this block works in a vertical guideway24 attached to the face of the window frame, the frame 13 being providedwith a lock 25 whereby the block 23 is locked in either upper or lowerposition, as desired.

Instead of block 23 attached to the lever back of the handle there maybe a metal guard, closing the opening in which the lever operates andextending under a guideway so as at all times to be under a thumbscrewwhich may be screwed down so as to hold the lever firmly at any point.

It is of course to be understood that my invention is not limited to theparticular devices for operating the frame 13 or the wedge and rodconstruction. for forcing the sash guide towardand from the windowsashes. While the mechanism illustrated constitutes the preferred formin which the invention is to be embodied, other mechanical movements maybe employed instead, for example, eccentrics pivoted on the window framepressing against the back of the sash guide might be employed.

As stated above, the sash guide extends from top to bottom of the windowand is slotted at the top to receive the edges of the pulleys for thewindow weights. The flanges at the edges of the sash guide are, however,continuous from end to end, and consequently when the window is closedand the sash guides clamped against the sash rails a weather-tight jointwill be formed throughout the length of the upper sa'sh between the sashand the sash guide and also between the sash uide and the window frame.There will also be a weather-tight pressure between the sashes wherethey overlap and between the inner face of the lower sash and the adwillgive way before the window willmove,

and unless the handle of the lever 21 be posi-' tively pressed downwardthe windowsvill remain locked, for the inclined faces of the blocks 15are very gradual and under the pressure brought about by the clampingaction. the frame 13 will be held in place until positively elevated.

1 inseam:

It will be understood, of course that it is not necessar to have sashguides at both sides of the win ows for adjustment in the mannerdescribed; The sash guide at one side may be movable and at the otherside may be of the samedesign but fixed in osition whreby the movementof the mova 1e sash guide will force the sash against the-fixed sashguide and thereby clamp the sashes at both edges. When so constructed,spring buttons may be inserted in the fixed sash guide to release thewindow when pressure on the opposite side of the sash is released. Whentwo movable sash guides are employed they may be coupled to receive thetop of the upper sash and bottom of the lower sash when the window isclosed, to thereby clamp-the window around its entire edge and make itsubstantially airtight. Such additional channels are, however, notnecessary, as ordinary tongue-andgroove metal weather stripping makesa'sufficiently tight joint at the top and bottom of the window for allpractical purposes. Such Weather stri pin-g is not, however,satisfactory at the side edges of the window"for the reason that if theen agement is tight enough to keep out the weather it makes the windowtoo tight to open and close freely.
